Implementation

[0021] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0022] like Figure 1 , 2 As shown, an optoelectronic slip ring includes a stator unit and a rotor unit; the stator unit has an M1 transmission section 11 and an M2 transmission section, and the rotor unit has an N1 transmission section 21 and an N2 transmission section; optical signals are transmitted between the M2 transmission section and the N2 transmission section; the M1 transmission section 11 has an M1 magnetic ring inductor assembly, and the N1 transmission section 21 has an N1 magnetic ring inductor assembly, and the M1 magnetic ring inductor assembly and the N1 magnetic ring inductor assembly are arranged correspondingly to realize electrical signal transmission.

[0023] The above-mentioned solution provided by the present invention, by setting up the M1 magnetic ring inductor component and the N1 magnetic ring inductor component, realizes the transmission of electrical signals in a non-contact manner, thereby solving the problem of easy wear of the traditional photoelectric slip ring using the brush-type contact structure for electrical signal transmission, and extending the service life of the photoelectric slip ring.

[0024] The specific operation is as follows: the stator unit has a motor body 10, and the rotor unit has a rotating base body 20. The rotating base body 20 is rotatably mounted relative to the motor body 10. The M1 transmission part 11 is mounted on the motor body 10, and the N1 transmission part 21 is mounted on the rotating base body 20. The M1 magnetic ring inductor assembly is mounted on the end face of the M1 end of the motor body 10, where the M1 end is the end of the motor body 10 closest to the rotating base body 20. The N1 magnetic ring inductor assembly is mounted on the end face of the N1 end of the rotating base body 20, where the N1 end is the end of the mounting base body closest to the motor body 10. Preferably, the end face of the M1 end of the motor body 10 has an M1 annular groove, and the M1 magnetic ring inductor assembly includes an M1 inductor coil, which is assembled in the M1 annular groove. The end face of the N1 end of the rotating seat body 20 has an N1 annular groove, and the N1 magnetic ring inductor assembly includes an N1 inductor coil, which is assembled in the N1 annular groove. The M1 and N1 inductor coils are arranged in a gap-like relative arrangement. This method ensures the relative assembly of the M1 and N1 magnetic ring inductor assemblies while avoiding complicating the structure of the photoelectric slip ring, thus reducing production costs. The structures of the M1 and N1 magnetic ring inductor assemblies are identical, as detailed below. Figure 3 As shown, the M1 magnetic ring inductor assembly includes a circular inductor core 112, which is mounted on the N1 end or the M1 end. A through hole is provided in the middle of the inductor core 112, and an annular groove is provided on the outer end face of the inductor core 112. The annular groove constitutes the M1 annular groove or the N1 annular groove.

[0025] The preferred embodiment is as follows: The motor body 10 has a rotatably mounted shaft, which is a hollow shaft. The M2 transmission section and the N2 transmission section are mounted at both ends of the shaft. The N1 annular groove, the M1 annular groove, and the shaft are arranged concentrically. A fixed base body 19 is installed at the other end of the hollow motor. The fixed base body 19 has an M mounting hole, and the rotating base body 20 has an N mounting hole. The M mounting hole, the shaft cavity, and the N mounting hole are arranged sequentially. The M2 transmission section includes an M fiber optic beam collimator assembly 12 mounted in the M mounting hole. The M fiber optic beam collimator assembly 12 is connected to the optical fiber in an external optical fiber connector. The N2 transmission section includes an N fiber optic beam collimator assembly 22 mounted in the N mounting hole.

The M wire harness 14 is connected to the M1 inductor coil through the M1 notch. An N1 notch is provided around the edge or bottom of the N1 annular groove. An N channel for arranging the N wire harness 24 is provided on the electric rotary seat body 20. The N wire harness 24 is connected to the N1 inductor coil through the N1 notch.

[0026] An encoder 16 is mounted on the other end of the motor body 10. The motor body 10 is a coreless motor. The encoder 16 and the motor body 10 are connected to other external components via signal lines 17 and wires 18, respectively.

[0027] The above-mentioned solution provided by this invention can effectively extend the service life of the photoelectric slip ring. Furthermore, the hollow cup motor can rotate at high speed. During operation, the optical signal is emitted from the coaxial M-fiber beam collimation assembly, passes through the inner cavity of the shaft, and is received by the cup N-fiber beam collimator assembly 22; the optical path can also be transmitted in reverse. The electrical signal is transmitted through the inductively coupled M1 and N1 inductors. This achieves simultaneous rotational transmission of optical and electrical signals. Moreover, the photoelectric slip ring provided by this invention has high integration, small size, and is easy to install.
